The present invention relates to the connecting sleeve adapter of fluid-conveying hose, flexible pipe comprises at least one pipe box and is positioned at least one armor outside pipe box, and armor comprises multiple thread armouring part, and socketed pipe comprises:
At least one end section of-each armouring part;
-end arched member and the outer cover be fixed on the arched member of end, form Duan Duan receiving chamber between end arched member and outer cover;
The filler of-receiving chamber, end segments is buried within this material.
Particularly, pipeline is without connecting hose, for passing water body as ocean, lake or river conveying oil gas (hydrocarbon).
Background technique
The normative document API17J (without connecting hose standard) that such as this flexible pipe is set up according to API and APIRP17B (flexible pipe suggestion is used) formation.
Pipeline generally by one group with one heart and the layer of overlap formed.What it was counted as in the sense of the present invention " without connect ", therefore, when pipe bending, pipeline wherein at least one deck can relatively vertically move by adjacent layer.Particularly, without connecting tube be the pipeline of connecting material of the layer not being connected to form pipeline.
Pipeline generally passes water body, in the base assemblies of the fluid for being received in water bottom exploitation and for collecting with between the floating of distributing fluids or fixing surface components.Surface components can be semisubmersible platform, FPSO or another floatation element.
In some cases, in order at deep water production fluid, the length of flexible pipe is greater than 800m.The end of pipeline has socketed pipe, is connected, and connects for centre for connecting water-bed assembly with surface components.
These pipelines bear very large axial tensile force, especially pipeline be positioned at water body wherein very dark time.
In this case, the upper socketed pipe that pipeline is connected with surface components should bear very large axial tensile force, and this tension force may reach hundreds of ton.These power pass to socketed pipe by the stretching armor extended along pipeline.
Axial tensile force not only has higher mean value, and along with the vertical motion of surface components and pipeline continues change under the effect of the water disturbance caused at wave.
Axial tensile force change can reach tens tons, and continues to repeat in pipeline using process.Therefore, vicennial loop number may reach more than 20,000,000.
Therefore, need to ensure firmly to fix especially between stretching armor and socket body.
For this reason, in known socketed pipe, generally ensure the fixing of armouring by the friction between armoury wire and the epoxy resin being cast in the indoor that arch and outer cover are formed.
In addition, the capstan winch effect relevant with the spiral path of armoury wire also contributes to the fixing of armouring, the screw diameter that can be formed by the line changed in socketed pipe relatively this spiral increases this capstan winch effect at the diameter at length of flow (longueurcourante), such as increase this diameter gradually according to rising taper, then reduce this diameter along decline taper.
In addition, the distortion of hook-type, waveform or spirality can be formed in the end of each armoury wire, so that in the epoxy embedding, to realize the mechanical caging of resisting the tension force applied.These distortion produce the power set up needed for capstan winch effect.
This socketed pipe can not be entirely satisfactory.Sometimes, the fixed random time fatigue decline of stretching armouring.

Fig. 1 partly represents the first flexible pipe 10 according to the invention.
Flexible pipe 10 comprises the central segment 12 that Fig. 1 partly represents.Flexible pipe 10 comprises end sleeve adapter 14 (can't see in Fig. 1) at each axial end of central segment 12, and its relative section is shown in Fig. 2.
With reference to Fig. 1, flexible pipe 10 forms fluid and the central passage 16 of preferably petroleum fluids flowing.Central passage 16 is along axis A-A ' between the upstream extremity that extends in pipeline 10 and downstream, and through socketed pipe 14.
Flexible pipe 10 is for being arranged in fluid especially oil gas production equipment through water body (not show).
Such as water body is sea, lake or ocean.Such as the water depth at fluid mining apparatus place is between 500m to 3000m.
Fluid mining apparatus comprises the water surface especially floatation element and water-bed assembly (not show), and they are connected to each other by flexible pipe 10.
Flexible pipe 10 is " without connecting " pipeline (English represents with " unbonded ") preferably.
When hose bending, at least two adjacent layers of flexible pipe 10 can free of one anotherly vertically move.Such as, describe this pipeline in the normative document API17J that API (API) delivers and APIRP17B.
As shown in Figure 1, pipeline 10 is formed around axis A-A ' multiple concentric layers, they centrally section 12 extend to the socketed pipe 14 being positioned at pipe end continuously.
According to the present invention, pipeline 10 comprises and forms pressure sleeve and at least one first tubular casing 20 based on polymeric material.
Pipeline 10 comprises at least one stretching armor 24,25 be positioned at outside the first pipe box 20 in addition.
In addition, use desirably, pipeline 10 comprises inner frame 26, the pressure arch 28 between pressure sleeve 20 and stretching armor 24,25 and the overcoat 30 for the protection of pipeline 10 in pressure sleeve 20 in addition.
It is known that pressure sleeve 20 for will conveying fluid tight closure in passage 16.Pressure sleeve 20 is formed by polymer material, such as, based on polyolefin, as polyethylene, as based on polyamide, as PA11 or PA12, or as polyvinylidene fluoride (PVDF) based on fluorinated polymer.
Such as the thickness of pressure sleeve 20 is 5mm to 20mm.
When there is inner frame 26, such as it is formed by the metal tape section bar being wound in spiral.The spiral of metal tape preferably overlaps mutually, can bear radial flat pressure like this.
In this example, skeleton 26 is positioned at pressure sleeve 20.Due to the geometrical shape of skeleton 26, this pipeline is called " roughbore " by English.
As modification (not show), flexible pipe 10 does not have inner frame 26, then English is called " smoothbore ".
The spiral winding forming the metal tape section bar of skeleton 26 is short spacing, and namely its absolute value helix angle is close to 90 °, is generally 75 ° to 90 °.
In this example, pressure arch 28 is for bearing the power relevant with the pressure in pressure sleeve 20.Such as it is formed by the wire section bar be spirally wound on around pressure sleeve 20.Wire section bar generally has complicated geometrical shape, especially Z, T, U, K, X or I shape.
Pressure arch 28 is spirally wound on around pressure sleeve 20 with short spacing, and namely its absolute value helix angle is close to 90 °, is generally 75 ° to 90 °.
Flexible pipe 10 of the present invention comprises at least one armor 24,25 formed by least one microscler armouring part 29 spiral winding.
In example shown in Fig. 1, flexible pipe 10 comprises several armor 24,25, the inner armor layer 24 of the pressure arch that especially reclines 28 (or not having to recline during pressure arch 28 pressure sleeve 20), and by armoured layer 25 that overcoat 30 surrounds.
Each armor 24,25 comprises the longitudinal armouring part 29 be wound around around conduit axis A-A ' with long spacing.
" long spacing winding " says that the absolute value of helix angle is less than 60 °, is generally between 25 ° to 55 °.
The armouring part 29 of first layer 24 is generally according to the angle wound that the armouring part 29 with the second layer 25 is contrary.Therefore, if the winding angle of the armouring part 29 of first layer 24 equals+α, α is between 25 ° to 55 °, and the winding angle of the armouring part 29 of the second armor 25 such as contacted with the first armor 24 equals-α.
Such as armouring part 29 is formed by wire especially steel wire, or is formed by composite material tape, the belt of such as carbon fiber reinforcement.In the example shown in Fig. 2-5, armouring part 29 is formed by wire.
As will be seen, each armouring part 29 has the end section 34 entered in socketed pipe 14.End section 34 extends to the free end being arranged in socketed pipe 14.It also has vacation (pseudo) spiral path that axis is A-A ' in socketed pipe, is spirally wound on tapered jacket.
In the example shown in Fig. 2,3, to each armor 24,25, the end section 34 of armouring part 29 is to leave axis A-A ' diffusion mode from rear pick-up point 35 forward free end 36 extend.
Therefore the end section 34 of armouring part 29 is formed and opens forward and the basic truncated cone shape overcoat for being axle with A-A '.Therefore they form tulip shape end frustum.
As shown in Figure 4, the open angle α 1 of the end section 34 of the armouring part 29 of armoured layer 25 is greater than the open angle α 2 of the end section 34 of the armouring part 29 of inner armor layer 24.
In addition, to each armor 24,25, end section 34 side direction is separated from each other.Particularly, often pair end section 34 opposite side-edge between form the circular contact gap 37 can seen in Fig. 2.
In this embodiment, circular contact gap 37 extends between rear pick-up point 35 and front free end 36.Their circumferential width increases from back to front.
In addition, as will be seen, when manufacturing socketed pipe 10, end section 34 is as far as possible close to they minimum affined natural forms.Obtain this form by the end section 34 freely loosening each armor 24,25, what them can be made like this to take tulip shape disperses form.
Overcoat 30 permeates from flexible pipe 10 outside to inside for preventing and treating fluid.It is preferably formed by polymer material, especially based on polyolefin, as polyethylene, as based on polyamide, as PA11 or PA12, or based on fluorinated polymer, as polyvinylidene fluoride (PVDF).
The thickness of such as overcoat 30 is between 5mm to 15mm.
As shown in Figure 2, except end section 34, each socketed pipe 14 comprises end arched member 50 and the outer connection cover 51 from arch 50 axial projections backward.Outer cover 51 and end arched member 50 form the room 52 of the end section 34 accepting armouring part 29.
Socketed pipe 14 comprise that Fig. 2 schematically illustrates in addition around the front black box of pipe box 20 54 and the rear black box 56 around overcoat 30.
According to the present invention, socketed pipe 14 comprises the partition member 58 of the end section 34 of the armouring part 29 of at least one armor 24,25 of at least one interior subsides in addition.
In the example shown in Figure 4, each partition member 58 reclines from outward the end section 34 of armouring part 29 of inner armor layer 24, and the end section 34 of armouring part 29 from the interior armoured layer 25 that reclines.
Although Fig. 4 does not show, one or several partition member also can be made from the end section 34 of the armouring part 29 of the interior inner armor layer 24 that reclines.
Socketed pipe 14 comprises the back part 66 of the armor 24,25 remaining in socketed pipe 14 back zone in addition, and is arranged in room 52 and for burying end section 34 and the solid filling material 68 of partition member 58.
In this example, end arched member 50 is connected with another connecting sleeve adapter 14 for being made pipeline 10 by end flange (not show), or is connected with terminal equipment.
End arched member 50 has central bore, for receiving the end of pressure sleeve 20, and the fluid flowed through central passage 16 can be made to flow outside pipeline 10.
Outer cover 51 is included in axis A-A ' the tubular peripheral wall 70 that around extends.Peripheral wall 70 has and is fixed on end arched member 50 and the front edge 71 separated with armor 24,25 radial direction, and axially extends to the rear edge 72 outside end arched member 50 backward.
Outer cover 51 forms radially outer room 52.The axial forming chamber 52 forward in rear surface 73 of end arched member 50.
Front black box 54 contacts with arch 50 before being positioned at socketed pipe 14.In the embodiment of fig. 2, front black box 54 axially staggers forward with each partition member 58.
Black box 54 comprises in a known way for being embedded in phase capel 74 and mutually embedding flange 76 before on pressure sleeve 20.The effect that flange 76 pairs of arches 50 are locked makes front phase capel 74 radial deformation, and front phase capel 74 is embedded on pressure sleeve 20.In the example shown in Fig. 2, pipeline 10 comprises pressure arch 28, and front black box 54 comprises the intermediate stopper ring (not show) of pressure arch 28 in addition.Intermediate stopper ring is between front phase capel 74 with mutually embedding flange 76.
After rear black box 56 is positioned at rear holding member 66, and after front mutually embedding assembly 62.
It comprises at least one rear phase capel 80 mutually embedding with overcoat 30, and is fixed on the rear locking phase capel 82 of the rear ring 80 on outer cover 51 at rear edge 72 place of peripheral wall 70.
In example shown in Fig. 3,4, socketed pipe 14 comprises several along axis A-A ' dispersion partition member 58 mutually axially separately and between the end section 34 that the armouring part 29 of armor 24,25 is relative.
Each partition member 58 is completely contained in room 52.
Here each partition member 58 is made up of the continuous circular shape of axle centered by A-A '.In this example, annular has circular straightforward face, and as modification, it can be oval or polygonal, especially quadrilateral, such as trapezoidal, parallelogram, rectangle, rhombus, square, or triangle, pentagon or Hexagon.
Each partition member 58 is preferably formed by nonmetallic material, such as polyamide type plastic (nylon), elastomeric plastics, rubber or resin.
In addition, the hardness of these nonmetallic material is more than or equal to shoreA, and is preferably greater than or equal to 50shoreD.When select material be rubber or play plastics material time, this hardness prevents partition member 58 to be out of shape, and contact armor 24,25 time excessively flattened.
As shown in Figure 3, in the axial middle plane of Fig. 3, partition member 58 is formed along axis A-A in each end section 34 ' axis is to the contact area 90,92 separated.
Between two adjacent contact areas along A-A ' axis, the maximum spacing of 90,92 is at least greater than partition member 58 along axis A-A ' extend with contact area 90,92 relative largest axis at least two times.
Each partition member 58 has the upper contact area 90 with the end section 34 of the armouring part 29 of armoured layer 25, and the lower contact area 92 of end section 34 with the armouring part 29 of inner armor layer 24.
Partition member 58 forms packing material 68 with each and holds the middle contact gap 94 between section 34 between the region 90,92 that each end section 34 of holding section axially to separate contacts.
The forward and backward of each middle contact gap 94 is limited by partition member 58.It inwardly and outwards opens between partition member 58.It outwards and inwardly leads in the circular contact gap formed between every opposite end section 34 of armor 24,25.
Therefore, packing material 68 can be deep in each middle contact gap 94, directly to contact with the end section 34 between contact area 90,92 through circular contact gap 37.
This considerably increases the area of contact between packing material 68 and each end section 34, this adds increased the adhesive quality between packing material and each end section 34.Therefore the axial tensile strength of socketed pipe 14 is substantially increased.
In addition, exist in installation sleeve adapter 14 process partition member 58 can reduce make their mutually friction make the abrasive danger of end section 34.
In addition, the maximum radial thickness of each partition member 58 relative axis A-A ' is generally less than five times of contact area 90,92 middle-end section 34 maximum radial thickness.
This provide the maximum radial spacing between each armor 24,25 end section, this spacing, more preferably greater than 3mm, is especially greater than 5mm, and more preferably greater than 10mm.
This maximum radial spacing is generally less than 30mm, is preferably less than 20mm.
The thickness of the packing material 68 therefore in contact gap 94 is controlled and is limited, and this is conducive to its mechanical strength.
In the example shown in Fig. 3, the maximum radial thickness of each partition member 58 reduces from front to back.Therefore, the maximum radial thickness being positioned at the partition member 58 of foremost is greater than the maximum radial thickness being positioned at last partition member 58.This remains the natural shape of each armor 24,25 end section 34.
In addition, there is partition member 58 and limit contact between the armouring part 29 even eliminating armor 24,25 in socketed pipe 14, which increase fatigue resistance.
With reference to Fig. 2, the armouring part 29 of rear holding member 66 at socketed pipe 14 rear portion place around armor 25.
At rear holding member 66 place, the armouring part 29 of armor 24,25 is with the radius of spin spiral winding identical at central segment 12 place with them.
The shape of rear holding member 66 is circumferential band, and not obvious contributing to bears tension force.As below by explanation, especially its function prevents armor 24,25 chaotic during being installation sleeve adapter 14.
Solid filling material 68, as epoxy type thermosetting polymeric resin is arranged in room 52, around the end section 34 of rear holding member 66, arch 50 and armouring part 29.
Room 52 filled out substantially completely by packing material 68.It is preferably fluidly injected in room 52, and solidifies wherein, and the end section 34 of armouring part 29 is connected with arch 50 and/or outer cover 51.
As noted above, the circular contact gap 37 between the armouring part 29 abutting end section 34 of each armor 24,25 filled by packing material 68, and between two armors 24,25 each partition member 58 contact area 90,92 between middle contact gap 94.
Therefore, with reference to Fig. 3, each end section 34 of armouring part 29 has internal surface 96 and perimeter 98, and the two all contacts with packing material 68.
Packing material 68 is along axis A-A ' Liang Ge following contacts district 90,92 between each longitudinal component on, surround each end section 34 completely at the whole periphery of each end section.
Between packing material 68 with armouring part 29 armouring part 29 end section 34 2 side at least partially on exist to contact and ensure effectively to bear tensile force.Anchorage length can be reduced like this.
Such as, to the shear strength of interface 2MPa between armouring part 29 and packing material 68, girth approximates 30mm and the armouring part 29 of length 500mm can bear the tension force of about 30kN.To the layer (nappe) of 31 lines, this represents tension force socketed pipe 14 of the present invention being born to about 100kN, and if end section 34 does not have the longitudinal component contacted completely with packing material 68, this tension force is reduced to 500kN.
The assembling of socketed pipe 14 of the present invention is as follows:
During beginning, the different layers of pipeline 10 is cut to good length, so as arch 28, on there is the free end section 34 of the armouring part 29 of each armor 24,25.
Each end section 34 does not have radial deformation time initial, especially waveform or hook-type distortion.
Then, the rear holding member 66 of expansion form is arranged on around armor 25, is then locked at around armor 25.
Then, make the end section 34 of each armor 24,25 freely be in stable form, there is no external stress.
In addition, the end section 34 of the armouring part 29 of armor 24,25 is opened forward, has and leaves axis A-A ' shape of diverge forwards.
In addition, between abutting end section 34, there is circular contact gap 37.
The end section 34 of the armouring part 29 of armoured layer 25 is slightly lifted, and leaves axis A-A ', and they do not fold back, to introduce partition member 58 successively, make them abut in outside the end section 34 of the armouring part 29 of inner armor layer 24.The carrying out of this step does not have plasticity or the irreversible transformation of the end section 34 of armouring part 29, is namely limited in resiliently deformable, avoids embrittlement and the decrease of fatigue strength of material like this.
Then, the end section 34 of the armouring part 29 of armoured layer 25 is from the interior partition member 58 that reclines.
(not show) in a modification, partition member 58 enters in a similar manner, reclines in the end section 34 of inner armor layer 24 armouring part 29.
